STOVE-PIPE THIMBLE.

SPECIFICATION forming part of Letters Patent No. l247,450, dated September 20, 1881.

Application filed July 27, 1881. (Modell.)

To all whom it may concern:

Be it known that I, ELBRIDGE G. WEs'r, of Canandaigua, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Stove-Pipe Thimbles; and I do hereby declare that the following is afull, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part of this speciication.

This invention relates to stovepipe thimbles, and has for its object to combine simplicity in construction, saving of material, and effectiveness against lire or other dangers and inconveniences apt to arise when the stovepipe comes in direct contact with the wood or lnetallic casin g and to that end it consists in certain improvements in the construction and .arrangement of parts, substantially as will be hereinafter more fully described, and particularly pointed out in the claim.

In the annexed drawings, Figure l represents a plan view; Fig. 2, a vertical sectional view; and Fig. 3, a horizontal sectional view on the line x x, Fig. 2. f.

Corresponding parts iu the figures are denoted by the same letters of reference.

Referring by letter to the accompanying drawings, A designates a double cylindrical easing, constructed of tin, malleable or wrought iron, or any suitable material, and composed of the outer circular wall,B, and inner circular wall, C, leaving an air-chamber, D, between said walls, which are. connected by circular top and bottom plates, E F, respectively. vThese circular plates are provided with perforations G, to allow free circulation of air through the air-chamber between the outer and inner walls of the casing A, and have their inner edges beveled inward, as shown at H, over which beveled ends the edges I of the inner wall are turned or bent, thus effecting a saving in material.

J J are tinted rings, (which rings may as well be corrugated or beaded,) depending by means of hangers or brackets cfrom the plates E F inside the innerwall, C,of the casing, and serving to keep the latter in position, againstwhich rings the stove-pipe K rests when it is inserted through the thimble, thus also leaving an air space or passage between the stovepipe and inner casing, and keeping the former from direct contact with the latter.

By reference to the foregoing description, taken 4in connection with the accompanying drawings, the advantages and uses of my in` vention will be readily understood.

In cases where it is desired to pass a stovepipe through the ceiling of a room to the door above my invention will be found especially useful. Heretofore in such cases,owing to defects in. the arrangement and construction of the'thimbles, the wood-work has frequently caughtiire from the heatimparted by the stovepipe to the casingand from thence to the wood; but my invention obviates all liability of such accidents, there being two air-passages between the stove-pipe and wood-one between the stove pipe and inner wall of the casing, formed by the interposed uted,.corrugated, or beaded ring, and the other between the inner and outer walls ofthe casing, by means of the perforations in the top and bottom thereof.

The depending ring may be dispensed with altogether at one end ot' the thimble, as may also the circular bottom plate of the casing, without materially aii'ecting the nature of my invention. And my improved thimble will be found to he very effective in its objects,and at the same time inexpensive, durable, and simple.

I am aware that a iiutedring'is old in combination with a stove-pipe thimble, as shown in the patent to Woodruff, No. 106,528. I am also awareof thepatents to Brooks, No.88,727; Pierce and Smith, No. 109,838; Harris, No. 71,300, and Butt-les, No. 131,846; and I claim nothing therein shown; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

As an improvement in stove-pipe thimbles, the combination, with the hereindescribed double drum or casing, of a tinted ring suspended detachabiy between the said double drum and the stovepipe, substantially as herein described, for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have lle-reto affixed my signature in presence of three witnesses.
